An ink recovery means 8 which recovers an ink remaining on the inner peripheral face of a plate cylinder 2 right after printing and returns the recovered ink to an ink roller 22, is provided at a position slightly away from an inner printing nip part of the plate cylinder 2 toward the downstream side.
